Chop the cabbage and onion. Peel and dice the potatoes, and prepare the carrots if needed. Add the cabbage, onion, potatoes, carrots, green beans, and diced tomatoes to the Instant Pot insert. Season lightly with salt.



If using homemade meatballs, shape and brown them lightly in a skillet, then set aside. Slice the summer sausage into rounds and cut each round into quarters. Slice the hot dogs into bite-size pieces.



Place the meatballs, summer sausage, and hot dogs over the vegetables in the pot. Add the mushroom broth, celery salt, white pepper, garlic powder, and more salt if needed. Stir gently just enough to distribute the seasonings.


Cover and cook on the slow cook setting for about 5 1/2 hours, or until the vegetables are tender and the flavors have blended well.



While the soup cooks, pat the tofu dry with paper towels and cut it into bite-size pieces. Heat the oil in a wok or skillet over medium-high heat, then fry the tofu until lightly golden on all sides.


Transfer the tofu to a paper towel-lined plate and season immediately with a little salt, white pepper, and garlic powder. For the best texture, either stir the tofu into the soup during the last 40 minutes of cooking or serve it on the side for each person to add at the table.
